Schedule Management: Overseeing Project Timely Completion
PMBOK v8 Definition
Schedule management includes the processes required to oversee the project’s timely completion. The detailed project schedule should be flexible throughout the project to adjust for knowledge gained, increased understanding of risks and external influences, and value-added activities. Revising and maintaining the project schedule to sustain a realistic schedule should continue throughout the project.
Why It Matters for the Exam
This concept appears frequently in PMI exam questions testing your understanding of the fundamental purpose of schedule management—not just creating a schedule, but continuously overseeing timely completion. Questions often present scenarios where project changes occur, testing whether you know that schedule flexibility and ongoing revision are required, not a fixed baseline.
Key Points to Remember (for the exam)
- Core Purpose: Schedule management oversees the project’s timely completion—not just schedule creation
- Schedule Flexibility: The detailed project schedule must be flexible throughout the project
- Continuous Revision: Revising and maintaining the project schedule to sustain a realistic schedule continues throughout the project
- Adjustment Drivers: Adjustments occur for: knowledge gained, increased understanding of risks, external influences, and value-added activities
- Schedule Levels: Schedules can be created and defined at various levels; the project team specifies rules for relative granularity
- Communication Tool: The schedule serves as a tool for communication and managing stakeholder expectations
- Performance Basis: The schedule provides a basis for performance reporting and facilitates proactive identification of potential delays and risks
Typical PMI Exam Example
A project manager is leading a software development project. During execution, the team discovers a more efficient technical approach that could save two weeks but requires reordering activities. The sponsor asks if the schedule can be modified. What should the project manager do?
Answer: Revise the schedule to incorporate this value-added activity, maintaining a realistic schedule throughout the project as schedule management requires flexibility for knowledge gained.
PMI Exam Traps
-
Trap: Thinking the schedule is fixed once approved Reality: The schedule must remain flexible and be continuously revised to remain realistic throughout the project
-
Trap: Confusing schedule management with only creating a schedule model Reality: Schedule management includes overseeing timely completion—ongoing monitoring, revision, and maintenance
-
Trap: Believing schedule adjustments are only for delays or risks Reality: Adjustments also occur for knowledge gained and value-added activities, not just problems
-
Trap: Assuming one schedule level is sufficient for all projects Reality: Schedules are created at various levels; the team specifies granularity rules for the schedule model
